Legislative bodies are groups of elected officials responsible for making laws and shaping public policy. They can exist at various levels, including local, state, and national, and typically consist of two chambers, such as the House of Representatives and the Senate in the United States. Members of these bodies debate proposed laws, known as bills, and vote on their approval. These bodies also play a crucial role in representing the interests of their constituents, overseeing government actions, and managing budgets. Legislative bodies ensure that the voices of the public are heard in the decision-making process, contributing to a functioning democracy.
